Plug/socket for attaching the air inlet pipe (separate ducts)
The plug (1) must be modified as detailed below before it can
be used:
– disassemble the plug (1) from the boiler
– remove the pre-cut bottom (2) from inside the plug
– turn the plug over and refit it on the opening it was removed
from, first slotting in the gasket (3). The cylindrical part
should be facing upwards; the first part of the piping will be
attached here.
NOTE:
If the combustion air inlet duct needs to be connected to
the right attachment, move the air inlet closing plate (4) from
the right to the left and proceed with modifying the plug (1) as
described above.
